My father is on amantadine. Why do some take amantadine and some take Sinement. We asked his nurse practitioner to put him on the capsule form because his hand shook so when he poured the liquid he had trouble taking a full dose. Do you think he should use the liquid in the morning? He also experiences leg cramps and curling toes. And is now having a great deal of difficulty getting into bed -- he sits down and swings his legs up but then he gets stuck there and can't seem to inch down. Any suggestions? How do people respond to the problem of not being able to stop when walking ... I really had a hard time blocking him to get him to pause and take a couple of deep breaths when we went for a walk last Saturday. he was out of breath but couldn't stop! Hannah
